Answer 1

[Ng KimAnhh]

5km² 400m² = 5400m²

18000000m² = 18km²

\(\dfrac{5}{4}< \dfrac{3}{4}\)

\(\dfrac{5}{6}< \dfrac{6}{5}\)

\(\dfrac{6}{8}=\dfrac{3}{4}\)

\(\dfrac{7}{3}>\dfrac{7}{5}\)

\(\dfrac{4}{6}=\dfrac{2}{3}\)

\(\dfrac{5}{15}=\dfrac{1}{3}\)

\(\dfrac{7}{14}=\dfrac{1}{2}\)

\(\dfrac{6}{24}=\dfrac{1}{4}\)
